Hausnummern Falsch, hier ist ein Restaurant/Bar.

Hier gibt es keine Richtungsfahrbahn. Die westliche Fahrbahn (hier Fahrtrichtung Süden gezeichnet) ist nicht Teil der L102 und allgemeines Fahrverbot (ausgenommen Anrainer und Radfahrer).

This whole campus is Singapore Polytechnic, and the map doesn't label it, whereas Ngee Ann Polytechnic is labelled.

Can someone confirm and fix if the houses numbers are viceversa?
